Industrial High Pressure Leak Repair

Our Remarkable Safety Record

Date: 10/04/2019

Online leak repair is a dangerous business. The materials, pressures, and situations involved are all hazardous so safety is a serious issue. SOS has never had a lost-time injury, and we plan on keeping it that way.

We've had three decades to run into every possible leakage situation and figure safe repairs. The safety awards we've received — from the Minnesota Safety Council, the North Dakota Safety Council and the Energy Coalition for Contractor Safety, among others — are evidence of our serious commitment to on the job safety. And we belong to several professional organizations to hone our best-practice methods. At SOS, training takes precedence. An important attribute of any new hire is mechanical ability, field expediency or situational awareness, and a good measure of it is required.

To minimize any possible job site hazards, we have a full-time safety director. We're proud of our 30 plus years of safe and successful leak repairs.

NSF Composite Wrap Pipe Restoration at Water Treatment Plant

Date: 06/5/2019

We did this job at a water treatment plant that serves about 1.3 million people in Illinois. To follow regulations, we installed our NSF certified composite for pipe restoration.

All the pipe was in extremely poor condition. There was extreme external pack rust, pitting, section loose, and rusting that was visible. The pack rust was so extreme that water was leaking from some of the areas. Even the Ultrasonic gauge was not able to give on accurate reading for majority of the time because of the level of pack rust.

Composite wrap is the best solution for restoring pipes at mentioned condition. Why?

  • It is odorless and solvent free, durable, impervious to fuel, most chemicals and solvent
  • It bonds to a wide variety of surfaces such as metals, composite, concrete, plastic and woods
  • It meets the requirement of ASME PCC-2 standard and is certified to ANSI/NSF Standard

To wrap the pipe with composite first we clean the equipment to be restored. Then we wrap the pipe with the composite.

Hot Well crack repair using Carbon Fiber Wrap

Date: 04/17/2019

We did the Hot Well concrete restoration at a facility in Wisconsin using Carbon Fiber Wrap. This hot well is used for storage of steam heat condensate water. Operational temperatures range from 180 to 210 degrees F. The concrete containment wall was cracked and was leaking in several places with running water in a few locations. The crack went through the entire thickness of the concrete wall and across 2/3 of the wall length and around the corner for 3 feet.

The hot well was drained of water to stop the flow of water through the cracks. This also allowed for the temperature of the well to go down to a workable level for epoxy resin. Surface preparation was done using a dry ice blaster to remove all loose material from the surface of the concrete. The surface was inspected to assure there were no areas contaminated with oils and there were none.

The crack in the concrete was inspected and it was found to go completely through the wall thickness. The crack width ranged from a few thousands to over .080 inch. A two-part epoxy gel formulated expressly for filling cracks was selected from SOS inventory and pumped into the crack. The crack was sealed from the inside to allow for complete filling of the crack void. This is especially important for the corner where there was no continuous support of the concrete wall at all.

With the crack filled and the wall now properly supported, the rest of the wall was examined for pits, voids and missing material. This was especially important in corners where the wall meets the ceiling, floor and the adjacent wall. SOS has an epoxy mix that is a very stiff, thick consistency suitable for wetting and filling these voids and allows for shaping into large radius fillets for inside corners.

After that carbon fiber cloth covered thoroughly with epoxy was placed on the concrete wall. Please contact us to learn more about our unique techniques and methodologies for concrete leak repairs.

Leak Repair and Pipe-Freezing to Replace on-line Valves and Gaskets

A customer called SOS to help with repairing two blown out butterfly valve gaskets on cooling water lines with no isolation from main header.

To use Pipe-Freezing method in the most efficient way, first we installed two valve housings to seal the leaks and stop the flow. Next, we installed two freeze plugs simultaneously. Once freeze plugs were in place, we removed the two valve housings. With the freeze plugs isolating the valves from the header the customer was able to successfully install new valves and gaskets.After the valves were installed, we removed our freeze apparatus and the ice plugs thawed.

We have experienced crews who are cross trained in multiple services to provide you with the best solutions efficiently. This coupled with our excellent safety record makes us unique.
